CASE REPORT
Fabrication and relining of dentures with permanent silicone soft liner: A novel way to increase retention in grossly resorbed ridge and minimize trauma of knife edge and severe undercuts ridges

The aim of this study is to suggest a technique to improve the retention of the prosthesis in grossly resorbed ridge and minimize the trauma of thin, atrophic knife edge ridge with severe undercuts. Significant numbers of patients seek treatment for edentulism throughout the world. In the current scenario, implant retained/supported prostheses have been considered a standard of care for rehabilitation of completely edentulous patients, but still this treatment modality is out of reach of many patients due to economic factor. In such patients, conventional removable complete dentures are considered for functional rehabilitation. However, in some of the patients with grossly resorbed ridges and knife edge ridges or ridges with severe undercuts, these prostheses have compromised retention and also continuously causes trauma to knife edge ridges and mucosa covering the undercuts during insertion and removal of the prosthesis thereby reducing the compliance of the patient. By incorporating, a layer of resilient permanent silicone soft liner on the tissue surface of a new or old denture is a novel way to reduce the trauma of thin and severe undercut ridges and also improve the retention of the prosthesis. This study described the successful functional rehabilitation of three completely edentulous patients with grossly resorbed, thin knife edge, and severe undercut mandibular ridges with permanent silicone soft liner. Permanent silicone soft liner act as a shock absorber, helps in equal dissipation of occlusal stresses, maintains an intimate contact with the underlying tissues and compressed during function thereby increasing retention and minimizing trauma by preventing a direct contact of hard denture base with compromised tissues.

Genetics and oral health

There is a lack of knowledge regarding genetic diseases and its prevention among general population an important premise is that a better understanding of the genetic etiology of the diseases can facilitate early detection in high risk subjects. It also helps in designing more effective intervention strategies. Exciting new technology based on the foundation of genetic research has the potential to further enhance the quality of life. Progress in the field will require training of a new generation of the scientists with requisite skills, as well as greater collaboration and interdisciplinary work. The traditional epidemiologic approach has proved useful for generating hypotheses and unraveling disease etiologies. But now it is possible to go beyond these methods and look inside the "black box" of the disease process which would be able to change the definition of the risk factors or clarify their location in the casual model.

Matrix metalloproteinases: A double edge sword

Dental caries is a dynamic process which results in demineralization of inorganic constituents and destruction of organic structure of the tooth. The basic mechanism of inorganic demineralization has been studied and documented well enough. However, the exact mechanisms and enzymes responsible for the organic matrix breakdown remain unknown. Matrix metalloproteinases (MMPs), a family of endopeptidases which are responsible for degrading all extracellular matrix components, which are expressed in normal dentin-pulp complex. MMP's are believed to act as double-edged sword since it causes progression of caries process and also helps in repair and defense mechanism initiated by caries in dentin-pulp complex. Several MMPs are also found in normal dentin-pulp complex cells and tissues, and they are considered to be involved in many physiological processes during the formation and maintenance of the dentin-pulp complex. This article gives a brief review of MMPs and its role in oral health.

Objectives: The present study was undertaken to assess the knowledge and attitude of the graduating dentist with respect to various aspect of hepatitis C. Materials and Methods: A cross-sectional survey using a self-administered, structured, and pilot tested closed-ended 26-item questionnaire was completed by 99 dental students from Faculty of Dentistry, Sebha (Libya). Descriptive analysis was carried out, and Chi-square test was used for intergroup comparison. Results: Overall 54.5% students reported that their knowledge with respect to hepatitis C virus (HCV) infection was inadequate. 45.5% participants felt that books were the most common source for acquiring HCV information. Only, 44.4% participants were willing to treat high-risk HCV, patients. 70.7% interns feel that the dentists should not have the right to reject treating an HCV patient. 83% of the participants said that a dentist can contract hepatitis C from their patients if they do not use proper barrier techniques intergroup comparison showed statistically significant difference with issues related to contracting HCV from patient, HCV vaccine, treating patient in normal setting, perceptions toward HCV patients, and attitudes toward providing treatment. Conclusion: The study revealed that the knowledge of HCV among the dental students was not satisfactory, and their attitude toward HCV patients was discriminatory.
